means for pressing said parts gently together and drying them so that the product issues from the rear end of the machine Aber of balls 4 as best seen in Figs. 3 'and 4,

and mounted upon said balls-is the pastepot or box 5 which has grooves 6 along itsends so that it is movably supportedfupon the balls in` a manner which will be clear. Said paste box (best seen in Figs. 7, 8 and 9) has its front wall 7 vertical, its bottom 8 flat, and its rear wall 9 curved upward as shown in Fig. 9, and mounted on the upper edge thereof is a scraper 10 having asharp or knife edge 11 projecting forward toward the paste roller l2 so as to remove therefrom the surplus paste. This scraper bar is slotted as seen at 13, and screws 14 engaging said slots pass into the upper edges 'of the ends of said box so as to permit the adjustment of said bar. The trunn'ions of the paste roll are mounted in bearings 15 in the ends of the box, and one of them carries a gear wheel 16 and beyond that a sprocket wheel 17 connected by a chain 18 with a' second sprocket wheel 19011 a stub shaft 20 mounted in the frame and revolved by the pulley 21 from any suitable source. The

construction is such that, although -the .paste box may be moved backward and forward upon the brackets, the chain connection between the driving and driven sprockets causes the paste rollv to rotate constantly in the direction of the arrow in Fig. 4, so that paste is carried up. on itsf. ascending side, the surplus is scraped off by the scraper. The constant revoiution of lthe roll preventsthe paste from hardening thereon.

Beneaththe curved inner wall of the box is a cross bar 21 having an eye 22 to which is loosely connected one end of a rod 23 whose other end lis attached to a lever 25 (see Fig. 2), there being preferabl f a turn buckle 24 inserted within the lengt of this rod so `that by manipulating the lever 25' the entire paste box and its roll can be set forward or backward fora purpose to appear below, but the rotation of the paste roll will not be interrupted. Notehes 26A and 27 are provided in the framework 1, to be engaged by the lever 25 in its respective positions as seen in Fig. 2. When the lever isswung rearward the paste box and its roller will stand as seen in Figs. 4 and 5 and the single-faced strip S will be directed between the brackets 2, around the curved rear fwall 9 of the box '5, and beneathk a presser vroller 28 mounted in bearings 29 on the framework and the paste roller 5- it being my intention thatthe setting of the lever 25 andadjustment of the turn buckle 24 shall bring the paste box and its' roller sufficiently near the presser roller 28 to permit the single faced paper to pass between said rollers without being crushed and yet to cause the ribs of the corrugated paper to be borne against the ascending side ofthe paste roller with just suiiicient force to take the paste therefrom. Thus much of my machine constitutes what may be called the pastingA mechanism.

- The heating mechanism next to be described coperates with the pasting mechanism in the application of the face strip to the single-faced corrugated paper, and together these two mechanisms make up the attaching means above referred to.

The numeral 30 designates a rotating cylinder or drum whose trunnions- 31 are `iournaled in brackets 32 on the main frame, and one of them carries a gear 36 meshing with the gear 16 by which rotary motion is imparted to this drum whereas the other trunnion 33 is made hollow and is connected with a steam pipe 34 through a suitable valve 35. The numeral 37 designates a fixed ironing tube also carried by said brackets thence over the drum 30. where it is heated on its lower side, thence between said drum andthe tube 37 and beneath the latter where it is heated on its upper side, and by this tube it is applied to the ridges of the singlefaced corrugated paper -at a point where the stock and the facingjsheetpass between said tube and the pr sser roll 28 as best seen in Fig. 5. Thus -t e pasting means cooperates with the heating mechanism to attach the facing strip to the single-faced corrugated paper just at a time when said strip has been heated on both its under and upper sides and finally ironed out where it passes' beneath the tube, so that itis applied to the stock in a perfectly flat condition and whileit is hot or heated on its under surface and adheres to the pasted corrugated strip quickly and permanently. It willybe observed that the drum 30 rotates and therefore draws the paper ofi the roll 39' and heats the same on its lower face as it passes over said drum, but the tube 37. is stationary and therefore the paper slips beneath it and is ironed while it is heated on its upper face and applied to the stock. The ressing or drying means next to be described coacts -with the attaching means by drawin the ponwthe" bsyor ii'idxeges` of the corrufforaconsiderableperiod `of time y f y passing ,through the n andde rsytl'ie inished article at vi,endtherfeofready to beformed into lorcutfintosheets or strips of any de-v ngu; y g n i A airsoti shaftsAO are ,mounted 1n n atthe"`frontand rearuends ofthe fpectively, and each shaftv oeketf;` wheels Li2 just inside framework, the wheels bepperyand lower ksprocket y fThechains at right y th `machine are connected by `ggi anywsuitable type, and "by are pro ucedyupper and ower end elts` iwhose `,width is equal to or greater l "theiSlfOk andthe finished prod- "flengthiissufficient `for `the (machine.
